Long time no post. This statement really caught my attention; bravo if true
upgrading can happen, and someone can be put on it and do it right.
As Tom said, a little farther down the thread, we have talked over this many
times. I specifically remember, oh, about a dozen times I personally
have 'gadflied' this issue.
As one who now has a, let's see:
[root(at)pachyderm ~]# du /var/lib/pgsql/data -s
16668528 /var/lib/pgsql/data
[root(at)pachyderm ~]#
Yes, a 16GB inventory database, with in-database large object images. Anyway,
as one who does not look forward to migrating this the old-fashioned way (I
can just imagine how fas^H^H^Hslow a restore of all those large objects is
going to be; backup is slow enough (about 50 minutes on this Xeon 2.4GHz
box)), in place upgrade would cut this considerably; the database is not a
complex one, just a largish one. It's, let's see, only holding a little less
than 5,000 items with associated lo images (due to many factors, this is
handled through ODBC from Microsoft Access; it is a kludge, and a big one,
but it works very smoothly from the users' points of view, where item images
are literally 'dragged and dropped' from the digital camera straight to the
database).
So, anyway, looking forward to seeing some progress in this department... :-)
